Abstract

The protection circuit has a sum current transducer for detecting fault currents in a phase line (L) and a neutral line (N) and a network disconnection switch (21), operated via a switching stage (19). The condition of the protective earth line (PE) of the electrical network is monitored via the same fault condition detection device (14), for operation of the network disconnection switch.
